Bile Duct Cancer (Cholangiocarcinoma)

In many people no clear cause is found. Long-term inflammation of the bile ducts is a major risk, including primary sclerosing cholangitis (a chronic scarring disease of the bile ducts), bile duct stones, choledochal cysts and some parasite infections of the liver found in parts of Asia. Cirrhosis, chronic hepatitis B or C, and some inherited conditions are also linked to a higher risk. Having a risk factor does not mean you will develop the cancer.

It is an uncommon cancer overall, but it is more frequent in some regions of the world and in people with certain bile duct or liver conditions. It occurs mostly in older adults.

Treatment and decisions are usually made by a multidisciplinary team at a specialist centre. If you are fasting during Ramadan, talk to your team first: your health, medicines and treatment come before fasting, and fasting may be postponed for illness.

Doctors usually start with blood tests, including liver tests and tumour markers (blood substances that can be higher in some cancers, but are not enough on their own to make the diagnosis). Imaging such as ultrasound, CT and MRI of the bile ducts (MRCP) shows blockage and the size and location of any mass. A biopsy or brushings taken during ERCP (a scope procedure to look at and sample the bile ducts) or endoscopic ultrasound may be used to confirm the diagnosis. Cases are usually reviewed by a multidisciplinary team, meaning liver and bile duct specialists, surgeons, radiologists and oncologists together.

Lifestyle cannot cure this cancer, but it can help you cope with treatment and stay stronger.

• Go to all appointments and bring a family member if you can

• Stay as active as you feel able; gentle walking can help energy and mood

• Do not drink alcohol and avoid unregulated herbal products, which can harm the liver

• Ask for emotional and psychological support; it is a normal and important part of care

• Call your team promptly about fever, new jaundice or worsening itch

Maintaining weight and strength is a priority. A dietitian experienced in cancer care can tailor advice to you.

• Eat small, frequent meals rich in protein and calories if appetite is poor

• Fat may be poorly absorbed when bile flow is blocked; your team may advise on this and on vitamin supplements

• Drink enough fluids, especially if you are vomiting or have diarrhoea

• Avoid raw or undercooked fish and freshwater seafood if advised in your region

Medicines may be used to treat the cancer and to relieve symptoms. Your cancer team decides what is right for you.

• Chemotherapy (medicines that kill cancer cells) may be given after surgery or for advanced disease

• Immunotherapy or targeted therapy may be offered depending on tumour testing

• Medicines can ease itching, nausea and pain

• Antibiotics treat bile duct infection

• Tell your team about all other medicines and supplements you take

Procedures aim to remove the cancer when possible and to keep bile flowing.

• Surgery to remove the part of the bile duct or liver with the cancer offers the best chance of cure when it is possible

• Liver transplantation is considered in a few carefully selected patients at specialist centres

• Biliary stents (small tubes placed by ERCP or through the skin) open a blocked duct and relieve jaundice and itching

• Local treatments such as photodynamic therapy or radiotherapy are used in selected cases

Testing the tumour for specific gene changes is now part of care for some patients, because certain changes can be treated with targeted medicines. Combination treatment using chemotherapy and immunotherapy has also become an option for advanced disease. Your cancer team will explain what applies to you.

Outlook depends mainly on whether the cancer can be removed completely by surgery, which in turn depends on its location, size, spread and your general health. It is often found at a later stage, which makes treatment harder, so early assessment of jaundice matters. Even when cure is not possible, treatment can relieve symptoms, protect quality of life and help people live longer. Palliative care (care focused on comfort and quality of life) can be given alongside cancer treatment.

• Where exactly is my cancer, and what type is it?

• Can it be removed by surgery?

• Should my tumour be tested for gene changes?

• How will my jaundice and itching be managed?

• What support is available for me and my family?
